Mesut Ozil believes Arsenal has lost focus at times this season and need to add players to their club if they're going to compete for the title next season.

Ozil made those comments with the arrival of Pep Guardiola to Manchester City in mind.

"We know that it will not be easy and that we need reinforcements if we want next season to be on top here again," he added.

"It is again interesting to see who invests in who and how much the clubs do during the summer break.

"In addition, great coaches are coming into the league. I am thinking primarily of Pep Guardiola. Wherever he has been, he had success. He is a coach, keen on playing and his teams are feared.

"He will be imprinting his football in England, and people will be surprised."
